Abstract: The invention relates to new ?-vinyl carbonylated compounds corresponding to general formula (I), wherein R1, R2,R3, R4, R5 and Y are as defined in claim 1, their isomers, their diastereoisomers and acid addition salts or a pharmaceutically acceptable base. The invention also relates to a method for producing said compounds (I). It further relates to the use of said compound (I) as selective metalloprotease inhibitors, especially matrix metalloproteases 12 (MMP-12) and/or 9 (MMP-9). The compounds (I) are particularly useful for the prevention and/or treatment of chronic obstructive pulmonary disease (COPD), particularly emphysema induced by cigarette smoke.

Abstract: The present invention discloses compositions of novel DYRK1A protein inhibitors based on a 3,5-diarylazaindole motif and their preparation and use as medications in the treatment of cognitive disorders associated with dysfunction of DYRK1A protein, with Down's syndrome and with Alzheimer's disease.
